I'm probably getting old, but I don't remember if anyone followed
up on this, and I don't have time to check the archives right now.
so for the upcoming "feature complete" release, I've decided to
stick to (a).
for the next release, I suggest implementing a fourth alternative:
d) add a new unicode flag. if set, use LINEBREAK. otherwise,
background: in the current implementation, this decision has to
be made at compile time, and a compiled expression can be used
with either 8-bit strings or 16-bit strings.
a fifth alternative would be to use the locale flag to tell the
difference between unicode and 8-bit characters:
e) if locale is not set, use LINEBREAK. otherwise, use chr(10).
